QUIVER Consistent Object Sharing For Edge Services

QUIVER Consistent Object Sharing For Edge Services

ABSTRACT

We present Quiver, a system that coordinates service proxies placed at the “edge” of the Internet to serve distributed clients accessing a service involving mutable objects. Quiver enables these proxies to perform consistent accesses to shared objects by migrating the objects to proxies performing operations on those objects. These migrations dramatically improve performance when operations involving an object exhibit geographic locality, since migrating this object into the vicinity of proxies hosting these operations will benefit all such operations. This system reduces the workload in the server. It performs the all operations in the proxies itself.  In this system the operations performed in  First-In-First-Out process. This system handles two process serializability and strict serializabilty for durability in the consistent object sharing . Other workloads benefit from Quiver, dispersing the computation load across the proxies and saving the costs of sending operation parameters over the wide area when these are large. Quiver also supports optimizations for single-object reads that do not involve migrating the object. We detail the protocols for implementing object operations and for accommodating the addition, involuntary disconnection, and voluntary departure of proxies. Finally, we discuss the use of Quiver to build an e-commerce application and a distributed network traffic modeling service. QUIVER Consistent Object Sharing For Edge Services

EXISTING SYSTEM:

• In the existing system the proxies has been maintained in the critical path for each object updation or each proxy should connected with the centralized server.  
• The consistency was not maintained while sharing the object.
• If the proxy has failed means the object has been lost.
• The existing system supports only single-object operations, and provides weak consistency semantics.

PROPOSED SYSTEM:

• This system forms the proxies in the tree structure. It shares the objects within the proxies. It reduces the workload in the server.
• Quiver enables consistent multi object operations and optimizations for single-object reads that are not possible in these prior algorithms.

• This system recovers the proxy disconnection. The disconnected proxies maintained by alternate proxies or it will be maintained through server.
• This System use the kruskal’s algorithm for maintaining tree structure. It reduces weight age  in the tree structure.
• It holds the object even when the proxy has been disconnected.
